T This' inver ition ifelates ta-improvements a runway-fora sliding window-tango; panel. 1 Q- A'n object of the invention isto provide a runway for a pane, 'asf lass or-"other material, 5 which isconstructed asto close'itself against the entry of foreign substances-during such times as it is unoccupied by the pane. I

Another object is to provide a runway of the above character which is constructed so as to preclude vibration of a pane supported there- 'Another object is to provide a runway of the above character which is simple and inexpensive of manufacture.

.means described herein and disclosedin the ac- This invention relates to a runway for panels V in the runway, that portion of the runway unoc-.- cupied by the pane will close itself to the entry 10 of water, dirt or other foreign substances. V

The runway structure comprises a base portion 7 of rubber, fibre or other suitable material, having longitudinal parallel grooves or depressions 8 therein for forming the sides 9 which may be flexed centerward toward one another for diSDuSitiOIl at an angle to the base portion '7 as indicated in Fig. 1. Although the sides 9 are shown integral with the base portion, the sides may be hingedly mountedupon thebase portion by any other suitable means. Felt strips or contact members 10 may be glued or otherwise secured to the base portionand to thesides, to provide abutmentsfor the panel or pane to slide upon. f

These and other objects are attained by the- In the sides into f contactingr"elation .a sj-in d 7 Fig.1.; Said means consists offthe, resilient niembers 1=l;5;each"ofwhiclrcomprisesa clinchfportion or bead' l2wliich may be clinched ov'erf the free edges 13 of the sides 9. Extending outwardly '60 from each bead portion is a skirt or extension 14 having a sliding contact portion 15 for abutment upon the side walls 16 of the panel. The sliding contact portion may be formed by simply bending the free edge of the skirt upon itself so as to preclude excessive friction between the skirt and theside wall 16. The members 11 preferably are of resilient metal of anon-rust nature.

The skirts 14 diverge from the sides 9' from the bead portion toward the groove or hinge porthe resilient membersll may be secured to the sides 9 in a manner such-as to cause. actual contact between the free edges of the sides rather than between the metallic beads as indicated in Fig. 1. "The base portion '7 of the runway may be secured to the bottomwall'of the panel '5 by 7 any suitable means such as cement, or nails 17. e From the foregoing it should be readily apparent that a simple and inexpensive means has been provided for closing that portion of the runway unoccupied by the pane 6. Said means also serves to preclude vibration of the panewithin 8 5 the-runway regardless of the relative position of the'g'lass withinthe runway. The device remains neat in appearance because of theabsence of edges to be cut or frayed by the panel orrglass pane. It is-to be understood thatvarious modifica-fi tions and changes in structural details of the device may be made, within the scope of the claims, without departing from the spirit of the invention.

What is claimed is; [V g 1. I n combination with. a support means hav} ing' a channelwith side walls and a bottom wall, a runway structure disposed within the I channel and comprising a body-having a base portion and opposite sides movable relatively to the base portion, yielding means comprising a bead-like I V portion disposed over an edge of each side, and a yieldable extension extending from the beadlike portion to a position between each side and 7 its adjacent channel side Wall, for. yieldingly urging into contacting relationship the bead-like portions on the opposite runway sides.

2. A runway structure of the class'described comprising a base portion and side walls hinged-' Q 7 1y connected to the base portion, the'side walls movable to angular positions With respect to the base portion, a member having a bead-like clamp portion clamped onto each side along-theatres edge thereof, and a skirt extending. from each bead-like clamp portion at an angle to the plane of its corresponding side;

4. A runway structure of the class described comprising a base portion and sides hingedly connected to the base portion, the sides being movable to angular positions with respectt'o' the base portion, a resilientmember mounted adjacent afree edge; of each side, and a skirt on each resilient member diverging. from the said free edgeand. adapted, for slidably contacting a wall of. a. runway support.

5. A runway structure of the class described comprising a base portion and integral sides each arranged for hinged movement toward one another upon the base portion, contact members on the base portion and sides, and a resilient member secured to each side, said resilient members each having a skirt with a free edge adapted to slidably engagea wall of a runwaysupport.

6. A runway structure of'the class described comprising a base portion and a side movable to angular positions with respect to the base portion, a member having a bead-like clamp portion clampedonto said side along the free edge thereof,. and a skirt extending from said' bead-like clamp portion at an angle to the plane of its corresponding side.

7. A runway structure of the class described comprising a base portion and a side of stiff mathe bead-like clamp portionat an angle to the
